John Oliver wants Trump publicist John Miller to appear on 'Last Week Tonight.'

"To be clear, this is not an invitation to Donald Trump, who has never and will never be invited here for an interview," the comedian stresses.

Should he ever want it — and if he exists — John Miller has a chair waiting for him to appear on Last Week Tonight.

Host John Oliver extended the invitation while mocking Donald Trump on his HBO show Sunday.

The presumptive GOP presidential nominee was accused on Friday by the Washington Post of masquerading as his own PR man, going by the moniker "John Miller" during a 1991 phone interview with People magazine to boast about himself to an even greater degree.

Although the report — and many critics — have said the voice on the 1991 call is Trump, the billionaire businessman denied the allegations.

"No, I don't think it — I don't know anything about it. You're telling me about it for the first time, and it doesn't sound like my voice at all," Trump said Friday on the Today show. "I have many, many people that are trying to imitate my voice, and you can imagine that, and this sounds like one of the scams, one of the many scams — doesn't sound like me."

This retort exasperated Oliver.

"It's clearly you!" Oliver exclaimed.

And that's when the comedian invited John Miller on his show to settle the matter.

"To be clear, this is not an invitation to Donald Trump, who has never and will never be invited here for an interview," Oliver said.

To sweeten the deal, Oliver threw in some items John Miller might like, such as an overcooked steak and a hand mirror.
